Description

Technical Field

[0001] This utility model relates to the field of measuring tools, and in particular to a measuring tape. Background Technology

[0002] A measuring tape is a retractable measuring tool used to measure the length, width, height, and other dimensions of an object. A measuring tape typically consists of a housing, a tape retractable into the housing, and a hook at the end of the tape.

[0003] Generally, when it is necessary to measure the size of an object, the measuring tape is pulled out from the tape measure and fixed to the edge of the object by the hook to measure the size of the object. When the measurement is completed, the measuring tape automatically retracts into the measuring tape.

[0004] Currently, the tape measure retracts quickly, generating significant impact. This causes the gap between the hook at the end of the tape measure and the tape to widen, resulting in the measured dimensions including the length of the gap between the hook and the tape, thus reducing the accuracy of the measuring tape. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a measuring tape that can solve the problem of reduced measurement accuracy.

[0006] This utility model is achieved through the following technical solution: The housing includes a receiving cavity for accommodating the measuring tape, and the housing has a measuring tape groove communicating with the receiving cavity; The measuring tape is housed within the receiving cavity, and the measuring tape includes a hook for fixing the edge of the object being measured, and the bottom of the measuring tape is provided with an anti-slip layer; When the measuring tape is used to measure the object, the measuring tape with the hook attached extends through the tape groove to measure the object. After the measurement is completed, the measuring tape is retracted and stored in the receiving cavity. The anti-slip layer is used to reduce the speed at which the measuring tape is retracted.

[0007] Furthermore, the housing also includes a shock absorber, which is disposed below the tape groove. The shock absorber is used to cushion the tape when it is retracted, so as to reduce the impact force of retracting the tape.

[0008] Furthermore, the measuring tape also includes protective side shells, which are disposed on both sides of the housing.

[0009] Furthermore, the measuring tape also includes a marking plate, which is disposed on the surface of the protective side shell.

[0010] Furthermore, the measuring tape also includes a tape fixing component, which is used to fix the tape when measuring the object being measured, and the tape fixing component is disposed within the receiving cavity.

[0011] Furthermore, the tape fixing assembly includes a pressure spring and a rotating component. The housing also includes a vertical shaft, which is disposed within the receiving cavity above the tape groove. The rotating component has a shaft hole in its middle, and the rotating component is clearance-fitted with the vertical shaft through the shaft hole, so that the rotating component is fixed within the receiving cavity and can rotate around the vertical shaft. One end of the pressure spring is fixed to the inner wall of the receiving cavity, and the other end is fixed to one end of the rotating component.

[0012] Furthermore, the measuring tape also includes a button assembly for controlling the tape fixing assembly to fix or release the tape; When the ruler needs to be fixed, the button assembly controls the rotating member to rotate counterclockwise around the vertical axis and fixes the rotating member, thereby fixing the ruler and keeping the pressure spring in a stretched state. When the ruler needs to be released, the button assembly releases the rotating member and restores the pressure spring from its stretched state to its original state, thereby controlling the rotating member to rotate clockwise around the vertical axis and releasing the ruler.

[0013] Furthermore, the measuring tape also includes a connecting seat, which further includes a connecting lanyard, and the connecting seat is disposed in the housing at one end away from the tape groove.

[0014] Furthermore, the top surface of the ruler is provided with scale lines.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: This application discloses a measuring tape, which includes a housing and a measuring tape. The housing includes a receiving cavity for accommodating the measuring tape, and the housing has a measuring tape groove communicating with the receiving cavity. The measuring tape is housed in the receiving cavity and includes a measuring hook for fixing the edge of the object to be measured. The bottom of the measuring tape is provided with an anti-slip layer. When it is necessary to use the measuring tape to measure the object, the measuring tape with the measuring hook extends through the measuring tape groove to measure the object. After the measurement is completed, the measuring tape is retracted and housed in the receiving cavity. The anti-slip layer can reduce the speed of retracting the measuring tape, thereby reducing the impact force caused by the automatic retraction of the measuring tape and reducing the situation where the measurement accuracy of the measuring tape is reduced due to the increased gap between the measuring hook and the measuring tape at the end of the measuring tape, thereby improving the measurement accuracy of the measuring tape.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] See Figure 1 , Figure 1 The diagram shows a structural schematic of a measuring tape according to an embodiment of this application, which may specifically include a housing 1 and a measuring tape 2.

[0024] The housing 1 may include a receiving cavity 11 for accommodating the tape 2. The housing 1 has a tape groove 12 communicating with the receiving cavity 11, and the tape 2 is stored in the receiving cavity 11.

[0025] Specifically, the shell 1 can be made of resin, plastic, aluminum alloy or other materials. The shell 1 can be integrally molded to obtain the required shape, thereby obtaining the shell 1 including the receiving cavity 11; or the shell 1 can be divided into two sides, such as the left side of the shell and the right side of the shell, and then the left side of the shell and the right side of the shell can be integrally molded to obtain the shell 1 including the receiving cavity 11.

[0026] For example, the inner wall of the receiving cavity 11 may be provided with a winding shaft, and the winding shaft supports the drum, thereby winding the measuring tape 2 onto the drum. In addition, the measuring tape also includes a winding spring, one end of which is connected to the drum and the other end is connected to one end of the measuring tape, so that the measuring tape can be wound onto the drum by the winding spring, so that the measuring tape can be curled up and stored in the receiving cavity 11.

[0027] When it is necessary to use a measuring tape to measure an object, the measuring tape 2, which is equipped with a measuring hook 21, can be extended through the measuring tape groove 12 to measure the object. After the measurement is completed, the measuring tape 2 can be retracted and stored in the receiving cavity 11.

[0028] Specifically, the object being measured can be any object whose dimensions need to be measured.

[0029] In practical applications, users can pull out the measuring tape 2 stored in the receiving cavity 11 from the measuring tape groove 12. Pulling out the measuring tape 2 will cause the coiled spring connected to the measuring tape 2 to undergo elastic deformation, so that the coiled spring is in a stretched state. The coiled spring after elastic deformation will generate a restoring force, which tends to restore the coiled spring from the stretched state to its original state. After the measurement is completed, the coiled spring will be restored to its original state based on the elastic force generated by the stretching of the coiled spring. At the same time, the generated elastic force will be applied to the measuring tape 2 connected to the coiled spring, so that the measuring tape 2 will contract and be stored in the receiving cavity 11 under the action of the elastic force.

[0030] In one embodiment of this application, the ruler 2 includes a ruler hook 21 for fixing the edge of the object being measured.

[0031] Specifically, the hook 21 is located at the end of the ruler strip 2 away from the winding spring. For example, a mounting strip can be installed at the end of the ruler strip 2 away from the winding spring, specifically by means of a pin or rivet. The mounting strip can be a component integrally formed from two planes perpendicular to each other. One plane of the mounting strip can be fixed to one end of the ruler strip 2 by rivets or an axis, and the hook 21 can be fixed to the other plane in the mounting strip by rivets or an axis, thus positioning the hook 21 at the end of the ruler strip 2 away from the winding spring.

[0032] In one embodiment of this application, the bottom of the tape 2 is provided with an anti-slip layer 22, which is used to reduce the speed of shrinking the tape 2.

[0033] Specifically, the anti-slip layer 22 can increase the friction at the bottom of the tape 2, thereby reducing the speed of tape 2 retraction by increasing friction. For example, the anti-slip layer 22 can be a structure with dotted protrusions, striped protrusions, mesh patterns, anti-slip coating, etc.

[0034] In practical applications, dotted protrusions or striped protrusions can be applied to the bottom of the ruler 2 by stamping or etching to increase the friction at the bottom of the ruler 2 through the protruding structure; mesh patterns or patterns of different shapes can also be processed on the bottom of the ruler 2 to make the surface of the bottom of the ruler 2 rough and non-flat, thereby increasing the friction at the bottom of the ruler 2; or a coating with a high coefficient of friction can be applied to the bottom of the ruler 2 to improve the friction at the bottom of the ruler 2.

[0035] In practice, when the measurement is completed, the user will release the measuring tape 2. The measuring tape 2 will then retract back into the receiving cavity at a corresponding speed under the elastic force generated by the winding spring. The hook 21 set in the measuring tape 2 cannot enter the receiving cavity, causing the hook 21 to hit the housing 1 at a corresponding speed. This generates a large impact force at the connection between the hook and the measuring tape, which causes the gap at the connection between the hook and the measuring tape at the end of the measuring tape to become larger. This means that the measured dimension includes the length of the gap between the hook and the measuring tape, thereby reducing the measurement accuracy of the measuring tape.

[0036] Based on this, by setting an anti-slip layer 22 at the bottom of the tape 2, the speed of the tape 2 is reduced when the tape 2 is retracted, thereby reducing the impact force at the connection between the hook 21 and the tape 2, reducing the situation where the measurement accuracy of the measuring tape is reduced due to the increased gap at the connection between the hook and the tape at the end of the tape, and thus improving the measurement accuracy of the measuring tape.

[0037] For example, the top surface of the measuring tape is also provided with scale lines to measure the size of the object being measured.

[0038] See Figure 2 , Figure 2 This application provides a schematic diagram of the structure of a ruler according to an embodiment of the present application. Figure 2 As shown, the bottom of the ruler 2 is provided with an anti-slip layer 22, and a ruler hook 21 is installed at one end of the ruler 2.

[0039] In one embodiment of this application, the housing 1 further includes an anti-collision pad 13, which is disposed below the tape groove 12. The anti-collision pad 13 is used to buffer the tape 2 when it is retracted, so as to reduce the impact force of the tape 2 when it is retracted.

[0040] Specifically, anti-collision pads can be made of soft and elastic materials, such as silicone, polyurethane foam, and nitrile rubber.

[0041] In practical applications, when the measuring tape 2 needs to retract back into the housing 1 at a corresponding speed, the size of the hook 21 set in the measuring tape 2 is larger than the measuring tape groove 12, so the hook 21 cannot enter the receiving cavity. When the measuring tape 2 retracts into the receiving cavity 11, the hook 21 will hit the housing 1 at a corresponding speed, which will cause the gap between the hook 21 and the measuring tape to become larger, reducing the measurement accuracy of the measuring tape.

[0042] Based on this, by setting a bumper pad made of soft and elastic material below the tape groove 12, and by using the bumper pad 13 to buffer the hook 21, the impact force of the hook 21 hitting the housing 1 is reduced, and the gap between the hook 21 and the tape is reduced, thereby improving the measurement accuracy of the measuring tape.

[0043] In one embodiment of this application, the measuring tape further includes a protective side shell 3, which is disposed on both sides of the housing 1.

[0044] Specifically, the protective side shell 3 can be used to protect the housing 1, so as to reduce the impact force on the housing 1 when it collides, and reduce the probability that the measuring tape will not be able to extend or retract or the measurement accuracy will be reduced due to deformation of the housing 1 caused by the impact.

[0045] Typically, the protective side shell 3 can be made of plastic or alloy materials.

[0046] In one embodiment of this application, the measuring tape further includes a label plate 4. The label plate 4 is disposed on the surface of the protective side shell 3. The label plate is used to mark information such as the model, specifications, and measuring range of the measuring tape, so that the user can identify and use the measuring tape. Typically, the label plate is marked with text, pictures, or other information.

[0047] In one embodiment of this application, the measuring tape further includes a tape fixing component 5, which is used to fix the tape 2 when measuring the object being measured. The tape fixing component 5 is disposed in the receiving cavity 11.

[0048] Specifically, the tape fixing assembly 5 includes a pressure spring 51 and a rotating member 52. The housing 1 also includes a vertical shaft 14, which is located in the receiving cavity 11 above the tape groove 12. The rotating member 52 has a shaft hole in the middle. The rotating member 52 is clearance-fitted with the vertical shaft 14 through the shaft hole, so that the rotating member 52 is fixed in the receiving cavity 11 and can rotate around the vertical shaft 14. One end of the pressure spring 51 is fixed to the inner wall of the receiving cavity 11, and the other end is fixed to one end of the rotating member 52.

[0049] In one embodiment of this application, the measuring tape further includes a button assembly 6, which is used to control the tape fixing assembly 5 to fix or release the tape 2.

[0050] When it is necessary to fix the measuring tape 2, the button assembly 6 can control the rotating part 52 to rotate counterclockwise around the vertical axis 14 and fix the rotating part 14, so as to fix the measuring tape 2 through the rotating part 52 and make the pressure spring 51 in a stretched state; when it is necessary to release the measuring tape 2, the button assembly 6 releases the rotating part 52 and makes the pressure spring 51 in the stretched state return to its original state, so as to control the rotating part 52 to rotate clockwise around the vertical axis 14 through the pressure spring 51 and release the measuring tape 2.

[0051] See Figure 3 , Figure 3 A cross-sectional view of a measuring tape according to an embodiment of this application is shown, as follows. Figure 3As shown, the measuring tape 2 is coiled and housed in the receiving cavity 11 of the housing 1. A vertical shaft 14 is provided in the receiving cavity 11, and the vertical shaft 14 is located above the measuring tape groove 12. The measuring tape fixing assembly 5 includes a pressure spring 51 and a rotating member 52. One end of the pressure spring 51 is fixed to the inner wall of the receiving cavity 11, and the other end is fixed to one end of the rotating member 52. The button assembly 6 is generally located above the measuring tape fixing assembly 5. The housing 1 has an opening above the measuring tape fixing assembly 5 to install the button assembly 6 in the opening, so that the button assembly 6 is located above the measuring tape fixing assembly 5.

[0052] In practical applications, users can control the tape fixing component 5 to fix or release the tape 2 via the button component 6. Specifically, when the user needs to fix the tape 2, they can control the rotating component 52 to rotate counterclockwise around the vertical axis 14 via the button component 6, and fix the rotating component 52 so that the rotating component 52 presses the tape 2 against the inner wall of the receiving cavity 11, thereby fixing the tape 2. The pressure spring connected to the rotating component 52 is stretched, so that the pressure spring is in a stretched state. When the user needs to release the tape 2, they can release the rotating component 52 via the button component 6, that is, the rotating component 52 is no longer fixed, and then under the action of the pressure spring, the rotating component 52 rotates clockwise around the vertical axis 14, thereby releasing the tape 2.

[0053] As an example, the spring connected to the rotating member 52 can also be a tension spring, or any type of spring capable of causing the rotating member 52 to rotate.

[0054] In one embodiment of this application, the measuring tape further includes a connecting seat 7, which also includes a connecting hand rope 71. The connecting seat 7 is disposed in the housing 1 at one end away from the tape groove 12.

[0055] Specifically, the measuring tape can be suspended via the connecting rope 71 in the connecting seat 7 for easy storage or carrying.

[0056] See Figure 4 , Figure 4 A schematic diagram of another measuring tape provided in an embodiment of this application is shown, as follows: Figure 4 As shown, the bottom of the housing 1 has a ruler groove 12, and a shock absorber 13 is provided below the ruler groove 12. Protective side shells 3 are provided on both sides of the housing 1, and an identification plate 4 is provided at the center of the surface of the protective side shell 3. An opening is provided above the ruler groove in the housing 1, and a button assembly 6 is installed at this opening. A connecting seat 7 is provided at the end of the housing 1 away from the ruler groove 12.

[0057] This application discloses a measuring tape, which includes a housing and a measuring tape. The housing includes a receiving cavity for accommodating the measuring tape, and the housing has a measuring tape groove communicating with the receiving cavity. The measuring tape is housed in the receiving cavity and includes a measuring hook for fixing the edge of the object to be measured. The bottom of the measuring tape is provided with an anti-slip layer. When it is necessary to use the measuring tape to measure the object, the measuring tape with the measuring hook extends through the measuring tape groove to measure the object. After the measurement is completed, the measuring tape is retracted and housed in the receiving cavity. The anti-slip layer can reduce the speed of retracting the measuring tape, thereby reducing the impact force caused by the automatic retraction of the measuring tape and reducing the situation where the measurement accuracy of the measuring tape is reduced due to the increased gap between the measuring hook and the measuring tape at the end of the measuring tape, thereby improving the measurement accuracy of the measuring tape.
